Everything You Need To Know About Distribution Boards

A distribution board is more than just a box; it is a whole system with neutral linkages, an earth leakage device, and interconnecting cables all designed to ensure appropriate electrical distribution in your house or building. The primary cable enters the distribution board and is then routed to secondary circuits such as lights and plugs through breakers. Maintaining accurate power distribution is critical for the optimal performance of the device and is essential for home and appliance safety.

Purpose of a distribution board

The main switch, circuit breakers, bus bars, earth leakage unit, bypass equipment, and other switches are usually found on a power distribution board. All of these things work together to protect the electrical distribution system and linked electrical equipment from harm caused by various problems like short circuits, overload, earth leakages, and so on. The structural and technical properties of electrical distribution boards may vary depending on the specifications in a given country.

Below are three essential components of a distribution box:

Fuse Box

The most important purpose of a fuse box or breaker panel is to provide power. When too much power runs across a circuit for whatever cause, a fuse will blow or the circuit breaker will trip. This protects equipment from damage and, more crucially, prevents the overheated wire from causing fires.

  • Circuit breakers

Through the metre, the main cables from the electric company give power to your home. Power is driven from the metre to the main panel’s huge circuit breakers, which turn the utility power on and off. Electricity flows to electrical distribution panels when the main breakers are turned on. Individual circuit breakers distribute energy to various outlets, switches, and appliances throughout the residence from these panels.


Isolators are designed for safety, allowing one to see the state of a circuit part before touching it. The isolator is a switch that isolates a circuit system component when it is needed. Electrical isolators are components of a distribution system that are designed to ensure proper safety and maintenance. Isolators are typically utilised at the breaker’s end to repair or replace it.

A few safety tips to keep in mind while handling distribution boards

1. When the distribution board is not being physically handled, it must always be covered. This is to keep moisture, humidity, dust, and other contaminants from corroding the wires and fixtures. Blanking plates must be used to cover the vacant slots on distribution boards.

2. The distribution board should not be installed in an area where it can come into contact with water. Due to the risk of fire, these boards should not be mounted near a stationary cooking device.

3. Place a warning notice on the doors of the hidden metal box containing the distribution board. This will keep people from touching potentially dangerous components recklessly.
